6) How do I open the Qt application directly under Windows?

After the QT code is run under Window with Qt Creator, a matching buid-directory is generated in the catalog's sibling directory:

To enter this build-directory, the executable program is placed by default in the Debug folder:

Double-click to run this executable program, the results found that can not run, the following dialog box appears:

The reason is that the program does not find the appropriate library when it runs.

Next, we'll let the QT executable find the libraries it depends on by modifying the system environment variables.

A) Locate the path of the dependent library:C:\Qt\Qt5.5.0\5.5\mingw492_32\bin and then copy its path.

b) Modify Environment variables

My Computer (right-click)-Properties

Paste the previously copied C:\Qt\Qt5.5.0\5.5\mingw492_32\bin into the path, followed by a semicolon ";" Segmentation.

Then, rerun the executable program, if the program still does not run, restart the computer.
